Radius Identifiers
Check Convex Radius
B
Measure the radius of curves on tools, patterns, and dies. These identifiers are small enough to carry around.
Use style B identifiers as a radius gauge, diameter gauge, and ruler. They check for convex radii. Made of stainless steel, they resist corrosion.
Loupes with Measuring Scale
Magnify and measure in one operation. Two lenses provide distortion-free viewing. This loupe includes a general purpose scale that measures circles from 0.002" to 0.0625"; radii from 1/16" to 3/8"; angles up to 90° in 5° increments; lengths up to 0.5" in 0.005" increments; lengths up to 10 mm in 0.2 mm increments; and line widths from 0.016" to 0.250".
Optional thread accuracy scale measures the following threads per inch: 50, 32, 28, 24, 20, 18, 16, 14, and 8.
